Galaxy Store Screenshot Sizes and Rules (2026)

I read Samsung's Content Publish API reference and its Galaxy self check list on 31 October 2026.

This guide covers every listing image Samsung names, the text limits, and how to reuse a Google Play set.

You can fill in a Galaxy Store listing by hand, in Samsung's Seller Portal. The portal shows its hints field by field, and you only see them once you're signed in.

Samsung also runs the Content Publish API, which sends the same listing to the store from code. Its API reference lists every field with its size, format and limit. That makes it the clearest public source for the numbers below.

One caution applies. The reference describes uploads through the API. If Seller Portal shows a different hint on a field, follow the portal for that upload.

Samsung's reference names five kinds of listing images for an Android app.

1. 1Screenshots: 4 to 8, JPG or PNG, 320 to 3840 pixels, 2:1 at most.
2. 2App icon: one PNG, 512 x 512 pixels, up to 1024 KB.
3. 3Hero image: one JPG or PNG, 1200 x 675 pixels, up to 1024 KB, for games.
4. 4Edge screen images: two PNG files, 160 x 2560 and 550 x 2560 pixels, each up to 1024 KB.
5. 5Video: a YouTube link, shown in the first screenshot spot.

There's no feature graphic field like Google Play's. The sections below take each item in turn.

The reference gives the screenshot size as 320 to 3840 pixels. It doesn't say whether that range covers each side or only one.

The safe reading is to keep both sides inside it. A phone shot of 1080 x 1920 pixels does that easily, and so does 1440 x 2560.

Very large captures need care. A shot of 3840 x 2400 pixels sits right at the edge, so one pixel more would break the rule. Scale any capture above 3840 pixels down before you upload.

Tiny images fail as well. A capture smaller than 320 pixels won't pass, so scale it up or take it again on a larger screen.

Samsung also sets a maximum aspect ratio of 2:1. Put simply, the long side can't be more than twice the short side.

I checked common sizes against that rule. A 1080 x 1920 shot is 1.78:1, so it passes. Landscape 1920 x 1080 passes the same way, since the rule works in both directions.

Tall phone screens are the usual problem. A raw capture of 1080 x 2340 pixels comes to about 2.17:1, and 1080 x 2400 comes to 2.22:1. Both go past the limit.

Crop such shots, or place them in a frame on a canvas with a shorter ratio.

You must register 4 to 8 screenshots, Samsung's reference says. If you upload more than eight, only the first eight appear on the listing.

That makes order matter. Shoppers see your first screenshots before any others, so put your strongest screens at the front.

Four is the floor, so a listing with two or three shots won't go through. Plan at least four screens that each show something different, such as the main screen, a key feature, a result and a settings or sharing screen.

Eight is the useful ceiling. Anything past it is wasted work.

Both JPG and PNG are accepted for screenshots. PNG keeps text and flat colors sharp, while JPG suits photos and keeps files smaller.

Notice what's missing here. The reference gives no file size limit for screenshots, while it caps the icon, the hero image and the edge screen images at 1024 KB each.

So a large screenshot file isn't against any stated rule. Still, smaller files upload faster and load faster for shoppers on a slow connection.

If you build one set for both Samsung and Google Play, save PNG files without transparency. Google Play asks for that, as a later section shows.

Samsung's Galaxy self check list lists the most frequent reasons Galaxy apps fail review. One of them is about screenshots. It asks you to make sure the description and every screenshot accurately describe and portray the app.

The list also says screenshots should match what the app and the device show. In practice, show real screens from the current version, not a design that isn't built yet.

Captions and frames aren't banned by name. Keep the screen inside each frame a true capture, though, and don't promise a feature the app lacks.

If your app needs a login, the list also asks for a test account for the review team. A screenshot of a screen behind that login should match what they see once they sign in.

The same self check list covers other people's property. Titles, descriptions, tags and images must not violate anyone's intellectual property, such as brand names, logos and trademarks.

That rule reaches into screenshots. A capture that shows another company's logo, a famous game character or a celebrity photo can count against you.

Watch the small details too. Sample data in a screenshot often includes real brand names, like a list of shops or a chat with a known app's icon.

Replace those with made up names before you capture. It takes a few minutes and removes one reason for a failed review.

Galaxy Store has no video upload. Instead, you paste a YouTube link into the listing.

Samsung's reference says a screenshot of the video and its link then appear automatically in the first screenshot location. Your video becomes the first thing shoppers see.

The reference doesn't say whether your first screenshot moves back one place or how the eight shot limit counts the video. Check the listing preview after you add a link.

Since the video leads, the image Samsung takes from it matters. A clear shot of the app in use tells shoppers more than a logo on a plain background.

For an Android app, the icon must be a PNG file of 512 x 512 pixels, up to 1024 KB. JPG isn't listed for the icon.

The self check list adds a second rule. The app name and icon in Seller Portal must match what the device shows, such as in the app tray.

So don't upload a special store icon that differs from the one users get after install. If you redesign the icon, update the app and the listing together.

Our Play Store screenshot size guide covers Google's sizes, which you'll want if you list in both stores.

Games get one extra image. The hero image is a JPG or PNG of 1200 x 675 pixels, up to 1024 KB.

Samsung's reference says it appears at the top of the app detail page in some countries. You can use this field if your app sits in the Games category.

At 1200 x 675, the image has a 16:9 ratio, the same shape as a wide video. Key art from a trailer or a wide game scene fits it well.

Keep important text away from the edges. The reference doesn't say how each device crops the image, so a centered design is the safer choice.

The reference lists two more images, called edge screen and edge screen plus. Each is a PNG of up to 1024 KB.

The edge screen file measures 160 x 2560 pixels, and edge screen plus measures 550 x 2560. The reference describes both as an app icon or logo file.

Those are very tall, narrow shapes. A square logo won't fill them, so you'd need a design made for that format.

The reference doesn't explain where Galaxy Store shows these images. If your app doesn't need them, check whether Seller Portal lets you skip them before you spend time on a design.

Samsung counts listing text in bytes, not characters. The app title allows 100 bytes, and the long description allows 4000.

The short description is a single sentence of up to 40 bytes. It appears under the app title in the app list and in search results.

Bytes matter for some languages. The reference doesn't name the text encoding, but under UTF-8, the most common one, a basic Latin letter takes one byte and a Korean or Chinese character usually takes three.

So a 40 byte short description can hold only about 13 such characters. Count bytes, not letters, before you paste translated text.

If your app goes to two or more countries, English is required. The self check list says the default registration language must be English, with the title and description in English.

You can then add more languages. In the reference, each added language carries its own title, description and screenshots.

That's useful for apps with text in the interface. Shoppers in Germany can see German screens, while everyone else sees the English set.

Each language set follows the same screenshot rules. Localized shots still need 4 to 8 images inside the size and ratio limits.

Google Play's preview asset rules look very close. They ask for JPEG or 24 bit PNG with no transparency, at 320 to 3840 pixels, with the long side no more than twice the short side.

The counts differ, though. Google Play takes up to 8 screenshots per device type, while Samsung needs at least 4.

So a Play phone set of four to eight shots usually works on Galaxy Store as is. Check it once against the 2:1 rule and the content rules above.

If you also ship on Amazon's store, its fixed sizes differ, as our Amazon Appstore screenshot guide shows.

We make PlayMockUp, so weigh this part with that in mind. Our free mockup generator places a screenshot in a phone, tablet or laptop frame, with a gradient background and text.

Phone exports come out at 1080 x 1920 or 1440 x 2560 pixels. Both are 1.78:1, inside Samsung's 2:1 limit and its size range.

For a Galaxy Store listing, a Galaxy frame looks natural. Our device frame list includes the Samsung Galaxy S23 and S10+ and a Samsung tablet.

Whatever frame you pick, keep the screen inside it a real capture of your app.
